The comment by Krugman about Republicans wanting a fiscal crisis to dismantle the welfare system is somewhat hyperbolic. However there are plenty Republicans who claim to care about the deficit but when push comes to shove go for tax cuts instead and then point at the lack of revenues to justify cuts in the welfare system.
See here: https://en.wikipedia.org/wiki/United_States_public_debt#Meas... and refer to the first paragraph of the article of a definition of the two debt types.
You are out of your mind. Absolutely, 100 percent out of your mind.
Krugman dwells into conspiracy theory when he argues that republicans "enjoy" the deficit and with a nice slight of hand assigns the full responsibility for it to them. From random partisan hacks, sure, that how it goes, but for someone that likes to remind everyone that he has a nobel price, perhaps, just perhaps, we can expect a higher standard?
To say what should be obvious: Republicans don’t care about the deficit. They care about exploiting the deficit to pursue their goal of dismantling the social insurance system. They want a fiscal crisis; they need it; they’re enjoying it.
